Currently being considered for military application, the See All Open Sight technology can be had at an affordable price with our Original Mod-1 version. Known for it's durability, the See All Open sight is the ideal replacement for iron sights and the perfect alternative to battery-powered, temperature sensitive red dot sights. With no batteries required, the Open Sight with its built in Edge Glow technology, is perfect for low light conditions. Unlike red dot reflex sights, the Open Sight can not be effected by temperature swings making it perfect for both hunting and home defense. Have the peace of mind in knowing that you can rely on 100% accuracy...during the day or night. Great for crossbow applications as well!
